From 1992–1994, she played Darlene Chapinni, a devoted assistant to the titular host's sidekick Hank Kingsley, on The Larry Sanders Show. She was a regular for the first three seasons and replaced by Scott Thompson in 1994 after the first episode of the fourth season.
Doucett met Garry Shandling at a party and dated him from 1987 to 1994. In 1994, when their relationship ended, Shandling had her dismissed from The Larry Sanders Show. In turn, Doucett filed a lawsuit against Shandling and producer Brad Grey's company Brillstein-Grey Entertainment for sexual harassment and wrongful termination, which was settled out of court in 1997 for $1 million.
